I had a UTI a couple of weeks ago and ended up getting antibiotics from the chemist even though a GP and lab urine tests showed there was no infection. I had the 3 day course which cleared things up but now it is back again.
I've read on here somewhere that the tests don't pick up certain bacteria or low level infections (or something like that!) and that the 3 day antibiotics don't necessarily clear all of the infection and a 5 or 7 day course is better.
Can I go back to the chemists and ask for the longer course? If I do, what do I ask for?
